Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the large shear force generated by the elastic member used for resetting in the electromagnetic switch in the prior art during the movement of the moving iron core, which reduces the life of the elastic member and affects the electromagnetic switch. The technical problem of the breaking speed of the switch, so as to provide an electromagnetic switch that can reduce the shear force of the elastic part when the moving iron core moves, prolong the service life of the elastic part, and at the same time accelerate the breaking speed of the electromagnetic switch

Abstract

The invention relates to technical field of switches, specifically to an electromagnetic switch which comprises a bracket, a static iron core, a moving iron core, a transmission mechanism and an elastic part, wherein the static iron core, the moving iron core, the transmission mechanism and the elastic part are arranged on the bracket; the moving iron core is absorbed with the static iron core when being electrified and is separated from the static iron core when being powered off; the transmission mechanism is connected with the moving iron core in a linked manner; one end of the elastic partis connected with the transmission mechanism; the other end of the elastic part is arranged on the bracket through a hook; the hook comprises a guide section which is connected with one end of the elastic part in a sliding manner and is capable of enabling the elastic part to slide relative to the bracket in the radial direction of the elastic part in a reciprocation manner; the elastic part is suitable for exerting partial pressure to the transmission mechanism to enable the moving iron core to move away from the static iron core. By adopting the electromagnetic switch provided by the invention, the shearing force of a tension spring can be reduced when the moving iron core is moved, and the service life of the tension spring can be prolonged.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an electromagnetic switch. Background technique [0002] Electromagnetic switch, as the name implies, is a switch controlled by an electromagnet, that is, a combination of an electromagnet and a switch. When the electromagnet coil is energized, electromagnetic attraction is generated, and the movable iron core pushes or pulls the switch contacts to close, thereby connecting the controlled circuit. Electromagnetic switches are widely used in various industries. [0003] Electromagnetic switches in the prior art generally include a bracket, a static iron core, a moving iron core, an elastic member, and a transmission mechanism connecting the elastic member and the moving iron core. [0004] When the rated working voltage is applied to both ends of the electromagnetic coil, the moving iron core and the static iron core will generate electromagnetic attraction force, and the moving...
